Description of detection logic

IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed:Marked as improvement because 160.4796834034133 < 163.01287152998515.
IsChangePoint: Marked as a change because one of 1/15/2022 9:05:03 AM, 2/26/2022 10:27:55 AM, 3/1/2022 5:49:50 AM falls between 2/20/2022 5:50:14 AM and 3/1/2022 5:49:50 AM.
IsImprovementStdDev: Marked as improvement because 41.45048450514752 (T) = (0 -160810.57696607322) / Math.Sqrt((5680572.000263214 / (299)) + (171217.7283410908 / (6))) is greater than 1.967824097752068 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (6) - 2, .975) and 0.05320785385924233 = (169847.81466719712 - 160810.57696607322) / 169847.81466719712 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
